1.) Triangle is 1/2 x b x h (Which is option C)

2.) Rhombus is ½ × d1 × d2. (Which is option A)

3.) Trapezoid is ½(b 1+b 2)h or (b1 + b2)h/2 (Which is option B)

4.) Parallelogram is base x height (Which is option D)

Step-by-step explanation:

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2

good luck ! ; )

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
